AEROPLANIX CONSTBUGTEON Application led July 14, 1,930. Serial No. 467,669..

This invention relates to improvements in aeroplane construction and one of the objects of the invention is to provide new and improved means whereby the eiiiciency of the atmospheric pressure produced by the forward movement of the plane may be more eiiectively utilized in the lifting of the plane and holding it aloft.

Another object of the invention is to provide new and improved means whereby due to the increased utilization of the atmospheric pressure, the area of the wings of the plane may he relatively decreased.

Another object of the invention is to construct an aeroplane such that the stability thereof is considerably increased.

@ther objects of the invention will be in part obvious and in part pointed out hereinciter.

The invention accordingly consists in the features ofl construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims. v

ln the accompanying drawing, wherein l have illustrated a preferred form of embodinient of my invention,

Figure l is a perspective view of my improved aeroplane,

Figure 2 is a front elevational view thereof,

Figure 3 is a transverse. sectional view taken on the wings, said view being taken substantially on line 3--3 of Figure 2,

Figure 4 is a top plan view, partly broken away, of the upper surface of one of the wmgs, I l l Figure 5 is a perspective view, partly broken away, of one of the air current guiding vanes which are provided in the wings,

Figure 6 is a vertical sectional view taken on the line 6-6 o'f Figure 4.

Referring now to the drawing wherein similar reference characters refer to similar parts throu'ghgut the several views of the drawing, the reference numeral 1 denotes the fuselage of the plane vwhich may be of conventional form. Numeral 2 indicates the motorv and the numerals 3 and 4 denote the usual vertical and horizontal rudders provided in aeroplane construction. l

The reference numerals 5 and 6 denote the wings` ofv the plane which are secured in the usual manner to the fuselage l.

Referring now to the wing constructionwhich is illustrated in Figures 3 to 6 inclusive I provide in each wing a plurality of inclined vanes 7 which are spaced apart and suitably connected to the upperand lowerwalls of the wing. Each of the vanes 7 project belowv the lower wall 8 ofthe wing as at 9. rl`he projecting portions 9 which 'extend beneath the lower wall of each wing are preferably curved forwardly as clearly indicated in-Fig-` ure 3 of the drawing. Theupper ends of the vanes 7 are-curvedrearwardly and lie ush with the upper surface of the wing and form the' upper wall l0 thereof, said ends being spaced apart to form the longitudinally extending slits ll. I found it desirable to'vary the length of the projections 9 from the forward edge to the rearward edge of the wing whereby more eectively-to direct the air currents between the vanes 7 as indicated by the arrows in Fi 're 3, said air being directed upwardlyan rearwardly between the vanes 7 so as to impinge against the under surface of the curved upper ends of the vanes as also clearly indicated in Figure 3.

Extendin transversally of each are the supporting members ll to which the ends of the vanes are connected as shown in Figure 4 of the drawing. rlhese transversally extendin members l1 yare anchored to the front an rear portions of each wing. It will be noted that the vanes provide passageways. entirely through the wing from thev lower wall to the up rwall thereof. e

The vanes in the present instance are shown as plane members extending upwardly .and rearwardly from the lower wall of the wing. The particular shape of these vanes can, of course, be varied without departing -from'the spirit or scope ofthe invention.

Referring now tothe fuselage construction and particularly 'to' Figures' 1- and 2 of the drawing, it will noted that I have provided laterally projecting members12 and 13.

from the side walls and 15. of the fuselage...

These projecting members extend longitudinally of the fuselage upon each side thereof and are spaced apart as shown. I also mount a member 16 on the lower wall of the fuselage extending the same rearwardly as clearly shown in Figure 1, said member being disposed in parallel relation with the laterally extending members 12 and 13 of the fuselage. If desired I may provide a similar member upon the top of the fuselage extending the latter in the same direction and parallel with the members 12 and 13 and 16. These members are preferably of the same general construction as the wings 5 and 6 illustrated in Figures 3 to 6 inclusive and described hereinabove and are intended not only to increase the lifting power of the air currents but also to aid in stabilizing the plane.

Having thus described the construction of this embodiment of my invention, it will accordingly be seen that I have provided means whereby the lifting effect of the air through which the wings of an aeroplane are forced by the motor may be more effectively utilized, the air currents, it will be noted, passing entirely through the wings of the plane and impinging against the upper and rearwardly curved ends of the vanes.

The provision of the means upon the fuselage also aids in lifting .the plane as well as increasing its stability.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof,it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used.. in the following claims is intended to cove" all of the generic and specific features of t e invention herein described, and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween. I
